Description

Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a mold with a cooling channel layout. Background Art

[0002] The cooling channel is a channel designed in the mold, through which the cooling medium (usually water) flows to remove heat from the molten plastic, thereby achieving the effect of cooling and solidifying the workpiece material.

[0003] At present, the common method of opening a cooling channel in a mold is to pre-set a cooling pipe in the mold, or to open a hollow cooling cavity inside the mold. When the cooling pipe is pre-set in the mold, the cooling pipe cannot be laid inside the mold in a large area, and the heat dissipation effect is not good. When a hollow cooling cavity is opened inside the mold, the strength of the mold in the middle of the mold will be reduced, and the durability of the mold will be reduced. In addition, whether the cooling pipe is pre-set or a central control cooling cavity is opened, after long-term use, the cooling channel wall may be attached with debris, which will reduce the cooling effect and is inconvenient to clean. Therefore, improvement is needed. Utility Model Content

[0014] 1. The utility model provides a mold with a cooling channel layout, which is provided with a cooling channel assembly. Specifically, the support blocks between the outer part and the inner part can resist each other after the outer part and the inner part are assembled, and generate a certain supporting force. The vertical channels and transverse channels between the support blocks are used to cover the entire mold. Then, the connecting pipe can be used to input cooling water into the interior of the mold body, which ensures large-area cooling of the mold.

[0023] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0024] A mold with a cooling channel layout according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, see Figures 1 to 4 The present invention provides an embodiment of a mold with a cooling channel layout, comprising a mold body 1, wherein the mold body 1 is provided with an outer part 2 and an inner part 3, and a cooling channel assembly and a fixing assembly are provided between the outer part 2 and the inner part 3;

[0027] The cooling channel assembly includes several support blocks 401 and connecting pipes 402. The several support blocks 401 are respectively fixedly connected to the inner side of the top of the outer part 2 and the outer side of the inner part 3. The connecting pipes 402 are respectively fixedly installed at both ends of the outer part 2. The several support blocks 401 cooperate to form a vertical channel 403 and a transverse channel 404. The upper surface of the support block 401 on the inner side of the top of the outer part 2 is against the lower surface of the support block 401 on the outer side of the bottom of the inner part 3. The vertical channels 403 are arranged in a linear array on the inner side of the outer part 2 and the outer side of the inner part 3. The transverse channels 404 are arranged in a linear array on the inner side of the outer part 2 and the outer side of the inner part 3. The vertical channels 403 and the transverse channels 404 are perpendicular to each other, and the vertical channels 403 and the transverse channels 404 are identical to each other. One end of the vertical channel 403 is connected to the connecting pipe 402.

[0028] It should be noted that by dividing the mold body 1 into an outer part 2 and an inner part 3, a hollow cavity is provided between the outer part 2 and the inner part 3 as a cooling channel, and several support blocks 401 are provided in this cavity, and vertical channels 403 and transverse channels 404 are formed between the support blocks 401. The transverse channels 404 and the vertical channels 403 are connected to each other. When cooling water is input into the mold body 1 through the connecting pipe 402, the cooling water will enter through the vertical channel 403 and then flow into the transverse channel 404 and be distributed to each corner, and then circulate and discharge from the connecting pipe 402 at the other end of the mold body 1, thereby ensuring the distribution of the coolant. The support blocks 401 of the outer part 2 and the inner part 3 are arranged against each other. When the mold is squeezed during use, the cooling channel will be supported, thereby ensuring the strength of the mold and improving its durability.

[0029] Example 2

[0030] In some embodiments, as Figure 2 As shown, the fixing assembly includes a mounting groove 501, a sealing gasket 502, a screw hole 503 and a fixing bolt 504. The mounting grooves 501 are respectively at the edges of the outer component 2 and the inner component 3. The sealing gasket 502 is fixedly installed on the inner side of the mounting groove 501. The screw holes 503 are opened at the edges of the outer component 2 and the inner component 3. The fixing bolt 504 is fixedly installed between the outer component 2 and the inner component 3. The shape of the sealing gasket 502 matches the shape of the mounting groove 501. The screw hole 503 and the fixing bolt 504 are threadedly engaged. The inner component 3 is fixedly installed on the inner side of the outer component 2 through the cooperation of the screw hole 503 and the fixing bolt 504.

[0031] It should be noted that the mounting groove 501 and the sealing gasket 502 are provided to seal between the outer component 2 and the inner component 3, and the screw hole 503 and the fixing bolt 504 are provided to fix the outer component 2 and the inner component 3. The outer component 2 and the inner component 3 can be separated by disassembling the fixing bolt 504 so that the cooling channel opened between the outer component 2 and the inner component 3 can be cleaned to ensure the heat exchange effect of the cooling water.

[0032] Working principle: When in use, first assemble the outer part 2 and the inner part 3 by fitting the fixing bolts 504 and the screw holes 503, and install the sealing gasket 502 at the connection between the outer part 2 and the inner part 3 to ensure its sealing. Then, when the mold is in use, cooling water is input into the mold body 1 through the connecting pipe 402. The cooling water will enter through the vertical channel 403 and then flow into the horizontal channel 404 and be distributed to each corner. Then, it will be circulated and discharged through the connecting pipe 402 at the other end of the mold body 1, ensuring the distribution of the coolant. The support blocks 401 of the outer part 2 and the inner part 3 are against each other. When the mold is squeezed during use, it will support the cooling channel, thereby ensuring the strength of the mold and improving its durability.

[0033] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
